PATRICK H. OUMMINS, OF AMSTERDAM, NEW YORK.

SLED.

SPECIFICATION forming part of Letters Patent No. 311,126, dated February3, 1885.

Application filed September 10, 1884. (No model.)

To all whom it may concern:

Be it known that I, PATRICK H. GUMMINs, of Amsterdam, in the county ofMontgomery and State of New York, have invented certain new and usefulImprovements in Sleds; and I do hereby declare that the following is afull, clear, and exact description thereof. reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form part of this specification.

The object I have in view is to provide means whereby the shoes of asled may be easily, quickly, and securely attached to the runner; and tothese ends my invention consists, first, in constructing the shoeseither circular or semicircular in cross section, and the bottom of therunner with either convexity or concavity in cross-section, in which orupon which the shoes are laid; and, secondly, in turning theshoes atboth ends so as to embrace the rear and forward ends of the runners, allas will be more fully understood from the following description, whentaken in connection with the annexed drawings, in which Figure l is aperspective of the sled, and Figs. 2 and 3 crosssections of the runnerand shoe.

Similar letters of reference indicate corresponding parts.

A A represent the runners; B B, the supports; 0 O, the raves; D D, thecross-bars;

E E, the shoes, and a a bolts through the runners.

The construction of the sled is or maybe that in general use, and henceI need not enter into the details thereof. The shoes are round rod ironor steel of suitable diameter, and are jsufficiently long to admit oftheir being turned over the rear and front ends of the runner, as seenin Fig. 1. Each runner is formed along its bottom with a semicirculargroove, in which the shoes are placed. These grooves should be aboutone-half the diameter of the shoes, thus exposing a sufficient surfaceof the latter to protect the former from wear. It will be observed thatthe rear top portion of the runners are also grooved out to receive theends of the shoes, which are bent forward and forced down in saidgrooves.

grooves are made in the forward ends of the runners and raves, wherethey unite, and the shoes are likewise bent rearward therein, thuseffectually bracing and clamping said parts Similar l together, while atthe same time dispensing with the necessity of screws or bolts to fastenthe shoes to the runners.

It is obvious that instead of employing rodiron for shoes and groovingthe runner, as described, I may just reverse this construction by havingthe runner convex on this under side, and the upper portion of the shoesconcave, as seen in Fig. 3. -In either event the effect will be the samein dispensing with other means of fastening for the shoes. The frontand'rear ends of the shoe E are turned over the runner, and eitherembedded there in, as in the case where the round rods are used, or madeto hug the convex surface in the case where concave shoes are used. Bythese means the shoe is self-retaining, as set forth. The rivets orbolts, with their washers, which are applied to the runners near theirends, are designed to prevent the ends of the runners from splittingvertically when subjected to great lateral strain. These rivets or boltsre-enforce the runners at those points where the shoes are overturnedand locked, and are very important features of my invention.

I am aware that sleds have been provided with round iron shoes seatedinto grooves made in the runner, and secured on top of the latter, atthe ends thereof, by means of rivets. I do not therefore claim suchdevices.

What I claim,therefore, and desire to secure by Letters Patent, is-

l. The combination, with a sled-runner formed substantially asdescribed, of a selfholding shoe adapted to fit the top and bottom edgesof the runner, and having its ends overturned and locked thereto, asspecified.

2. The combination, with a sled-runner formed substantially asdescribed, of a shoe having overturned ends and adapted to fit the topand bottom edges of the runner, and the reenforcing rivets or bolts,substantially as specified.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
